Should Priests Correct People Who Kneel While Receiving the Eucharist?

A listener named John asks Father Dave about correct postures when receiving the Eucharist. "I've seen an increase of people kneeling to receive communion. I've heard Father Dave comment on this before, but I'm wondering if he can address this." John begins. "Every week, our priest calls out people for leaving after communion [before Mass ends]. Why not correct those who kneel to receive when that's not an option given to us by the Church, when not in a traditional Latin Mass setting?"
